FUEL MIXER.

5 State `ofIllinols, have invented a cert-ain new and `useful Improvement in Fuel Mixers, of which the following is, a full,

clear, concise, and exact description, reference being had to the accompanying drawings, forming a part ofthis specification.

My invention relates to devices for secur ing vaporization of fuel for combustion in engines and other devices. Described in connection with an internal combustion engine, it comprises a baffle or pair of wings disposed in the intake pipe and in the path of travel of fuel from the carburetor to the cylinder of the engine. The wings of the baille may be made of sheet metal having a width equal to the inner diameter of the pipe in which the baille is disposed. The wings are twisted in helical form so that the fuel and fuel vapor are given a whirling motion to break up any unvaporized globules of fuel and to thoroughly mix the gas. To assist in securing a highly combustible mixture, the baffle members are serrated to provide ridges against which the drops of fuel are deflected and are thus bro-ken.

An important feature of my invention is the arrangement of the baille members in such a manner as to prevent the fuel and fuel vapor from nassing through the pipe to theengine in a straight line without being subjected t0 the whirling effected by the helical wings. An important advantage in whirling the combustible mixture lies in the fact that it is thrown outwardly to the walls of the fuel pipe and highly vaporized, due to the warmth of the pipe. The device may be secured in the intake pipe of the engine in any suitable manner, but I have provided means comprising a gasket to whichthe mixer may be attached and sold ready for attachment between the flange of an ordinary carburetor and the flange of the intake pipe. A novel manner of attaching the mixer to the gasket is'employed.

The objects of my invention are:

First, to provide a device for mixing fuel forv combustion;

Second, to provide a device capable of Application filedlJuly 7, 1921. Serial No. 482,911.

manufacture andd sale independent of the Vengine onY which it is to be used; and

. Third, to provide a fuel mixer at a low cost.

My invention will be clearly understood by reference to the accompanying drawings, in which` Figures 1 and 2 are views in elevation of the wings forming thebafile member of the fuel mixer; Y v

Figure 3 is an elevational view of a fuel mixer attached to a gasket;

Figure 4: is a view of the device of Figure 3, showing method of locating same in an intake manifold of an engine.

Similar characters of reference refer to similar parts throughout the several views.

The baffle member comprises two wings 9 and 10, each of which is similar in construction and are adapted to fit one within the other by means of co-operating slots 11 and 12. The wings are made of sheet metal having a width substantially equal to the inner diameter of the fuel pipe and are twisted in helical form so that the opposing ends lie in planes substantially 90 degrees and preferably slightly more than 90 degrees apart. Each of the wings is serrated or corrugated to provide ridges and grooves, providing defleeting surfaces.

In the preferred embodiment of my invention, the wings 9 and 10 are provided with keys 13-13 adapted to be inserted in keyways 1li- 14: provided in the gasket 15. When the baille member is secured to the gasket 15 in this way the same is firmly held in place.

In Figure 4 I have shown a fuel mixer disposed in position, with the gasket l5 secured between ilange 16 of an ordinary carburetor, and flange 17 of the intake manifold of an internal combustion engine. As illustrated, I twist the wings 9 and 10 so that the opposite ends lie in planes at a sufficient angle apart so that fuel travelling through the. intake manifold is always deflected by the baffle and is prevented from passing through the pipe in a straight line. It will be seen that, due to the serrated surfaces of the wing members, any unbroken globules of fuel will be deflected and broken by contact with the serrated surfaces. As the intake manifold of an internal combustion engine is usually kept warm by the heat of the engine, the fuel passing through the pipe is highly vaporized, after being thrown outwardly to the inner wall of the manifold.v

lVhile I have shown the fuel mixer of my inventionattaehed to agasket ,for disposi.- tion between the flange o f yal oarburgetor and the flange of an intake manifold, i't will be apparentthat the mixer may be attached in any suitable manner in the path of travel of the fuel. e

What I claim is new and desire to secure by vLetters yPatent Aof, the United States f is l. A mixing device `forinsertion between the flanges 'of the intake manifold of 'an internal combustion engine comprising Ja gasket disposed adjacent said flanges, a baffle member having 'one end keyed in said gasket, said baille member comprising a-pai'r of twisted and ser/ratedy wings arranged to prevent the 4'passage of fuel through "the manifold in a straight path.

2. A mixing device for insertion between the flanges of the intake manifold of an internal combustion engine comprising a gasket, al baille member having one end keyed tos'aid'gasket, said baffle member comprising a pair of stepped Vhelical wings, the free end of yeach of said Wings" beingA at lg',reate r lthan right angle 'tothe keyed' 'ends of said wings.

* 3. ,A mixing device for insertion between the flanges of the intake manifold of an Y. linternal combustion engine comprising a gasket secured to said flanges, a baille member having Vone end keyed innsaidfgasket f said balile member comprising a pair o twistedwings provided i'vitli` steps,jeaeh of said wings being arranged so thatftle plane Aof t'lre freefeds thereof 7extends at an angle of 'substantially 90,0 from the plane lof the i key-ed end of Isaid wings'. n, i
